When he broke through at the tender age of 16, Jonny Lang was something of an oddity in blues. The native of Fargo, N.D., sounded like he’d put at least 80 years of hard living behind him and turned it all into classic, technically astounding blues. Now in his 30s, Lang is beginning to grow into his genre, and he’s never sounded better. His most recent release, Fight for My Soul, came out in 2013. With Ana Popovic.
